Google, the Internet search and mapping pany, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the pany’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the puters react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.

(答案→)B
解析：文章大意：文章介绍了Google, the Internet search and mapping pany所发明的一种无人驾驶汽车。同时表明了作者对这种无人驾驶汽车未来的乐观态度。
【小题1】B 主旨大意题。文章第一句话就揭示了文章的主题。“has developed a car that can steer without a driver”与“has developed a driverless car”同义。
【小题2】D细节理解题。“Engineers say the driverless cars are safer than autos with people behind the wheel because the puters react much more quickly than humans.”句中“the puters react much more quickly than humans.”与D项“the software responds to emergencies faster than a human driver”同义。
【小题3】A细节理解题。根据“Your car should drive itself. It just makes sense.你的车可以自动驾驶的。这是非常有意义的事情。”可以得出答案。
【小题4】D推理判断题。从文章最后一段的描述中，我们可以推断作者对于“Carbot”前景的态度是“乐观的”。
